Description
Die Erfindung betrifft ein Magnetventil mit einer Handhilfsbetätigung nach der Gattung des Anspruchs 1.The The invention relates to a solenoid valve with a manual override the genus of claim 1.
Ein
derartiges Magnetventil ist beispielsweise aus der
Man kann zwar gewöhnlich optisch die eingeschobene Position des Betätigungsglieds der Handhilfsbetätigung erkennen, allerdings nur bei genauem Hinsehen, sodass eine entsprechende Überprüfung einer Vielzahl von Magnetventilen sehr umständlich und aufwendig ist. Zusätzliche Sensoren, insbesondere Positionssensoren, zur Erkennung der Position des Ventilglieds machen ein Ventil kompliziert und teuer.you may be ordinary visually recognize the retracted position of the actuator of the manual override, but only on closer inspection, so a corresponding review of a Variety of solenoid valves is very cumbersome and expensive. additional Sensors, in particular position sensors, for detecting the position of the valve member make a valve complicated and expensive.
Eine Aufgabe der vorliegenden Erfindung besteht somit darin, ein Magnetventil mit einer Handhilfsbetätigung zu schaffen, bei dem die Stellung der Handhilfsbetätigung in einfacher Weise ohne zusätzliche Sensormittel erkannt werden kann.A Object of the present invention is therefore a solenoid valve with a manual override in which the position of the manual override in easy way without additional Sensor means can be detected.
Diese Aufgabe wird erfindungsgemäß durch ein Magnetventil mit den Merkmalen des Anspruchs 1 gelöst.These The object is achieved by a Solenoid valve solved with the features of claim 1.
In vorteilhafter Weise kann erfindungsgemäß der Verbleib des Ventilglieds beziehungsweise des Magnetkerns in der Arbeitsstellung bei vergessener Rückstellung der Handhilfsbetätigung in einfacher Weise durch Überwachung des Stromflusses beim darauffolgenden Einschalten erkannt werden. Zusätzliche Sensoren sind hierzu nicht erforderlich. Die Erkennung er folgt elektrisch, sodass ein entsprechendes Signal in einfacher Weise angezeigt und/oder an ein übergeordnetes System oder eine Steuerzentrale übermittelt werden kann. Auf diese Weise lassen sich auch bei einer großen Anzahl von Magnetventilen schnell und einfach diejenigen ermitteln, bei denen die Handhilfsbetätigung noch in der betätigten Stellung verblieben ist.In Advantageously, according to the invention, the whereabouts of the valve member or the magnetic core in the working position with forgotten provision the manual override in a simple way by monitoring the current flow are detected at the subsequent turn on. additional Sensors are not required for this purpose. The detection he follows electrically, so that a corresponding signal is displayed in a simple manner and / or to a parent System or a control center can be. In this way, even with a large number from solenoid valves quickly and easily determine those at which the manual override still in the pressed Position remains.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen des im Anspruch 1 angegebenen Magnetventils möglich.By in the subclaims listed activities are advantageous developments and improvements of the claim 1 specified solenoid valve possible.
Die Spulenstrom-Überwachungseinrichtung weist zweckmäßigerweise ein Strommessglied, insbesondere einen Strommesswiderstand, im Schaltkreis der Magnetspulenanordnung auf. Dieses bildet einen Bestandteil der Spulenstrom-Überwachungseinrichtung und ist somit unabhängig vom Magnetventil selbst beziehungsweise von dessen mechanischer Anordnung.The Coil current monitoring device points expediently a current measuring element, in particular a current measuring resistor, in the circuit the solenoid assembly. This forms part of the Coil current monitoring device and is thus independent from the solenoid valve itself or from its mechanical Arrangement.
In einer zweckmäßigen Ausgestaltung weist die Detektionseinrichtung einen Strom-Maximalwertspeicher für den Spulenstrom und eine bei Nichterreichen eines vorgebbaren Differenzwerts zwischen Spulenstrom und Strom-Maximalwert ein Signal in der Signalisierungseinrichtung erzeugende Schwellwertstufe auf. Dabei sind bevorzugt Einstellmittel zur Einstellung des vorgebbaren Differenzwerts vorgesehen, um Anpassungen an das jeweilige Magnetventil und dessen Stromverhalten vornehmen zu können. Zur Bildung des Differenzwerts ist dabei zweckmäßigerweise eine Subtrahierstufe vorgesehen.In an expedient embodiment the detection device has a current maximum value memory for the Coil current and a failure to reach a predetermined differential value between the coil current and current maximum value, a signal in the signaling device generating threshold level. In this case, preference is given to adjustment to set the predefinable difference value provided to adjustments to the respective solenoid valve and its current behavior to be able to. to Forming the difference value is expediently a subtraction stage intended.
Um mit derselben Spulenstrom-Überwachungseinrichtung neben der Erkennung einer nicht rückgestellten Position der Handhilfsbetätigung auch noch eine unkorrekte Bewegung des Magnetkerns erkennen zu können, sind in vorteilhafter Weise Mittel zur Erkennung eines zeitlich verschobenen Stromeinbruchs vorgesehen, wobei die Signalisierungsmittel zur Erzeugung eines diese unkorrekte Bewegung anzeigenden Signals ausgebildet sind.Around with the same coil current monitoring device in addition to the detection of an unreturned position of the manual override also to be able to recognize an incorrect movement of the magnetic core are Advantageously, means for detecting a time-shifted current collapse provided, wherein the signaling means for generating a this incorrect motion indicative signal are formed.
Im Falle von optischen Signalisierungsmitteln weisen diese bevorzugt wenigstens eine LED auf. In einer bevorzugten konstruktiven Ausgestaltung des Magnetventils ist ein den Magnetkern in der Ruhestellung haltendes Federglied vorgesehen, wobei sowohl bei Betätigung durch die Handhilfsbetätigung als auch bei einer elektrischen Betätigung die Bewegungskraft gegen das Federglied gerichtet ist.in the Cases of optical signaling means are preferred at least one LED on. In a preferred structural embodiment the solenoid valve is a magnetic core holding in the rest position Spring member provided, both when actuated by the manual override than even with an electrical operation the motive force is directed against the spring member.
